Would it be a problem if I installed .Net 1.0 and 2.0 on the same machine?
thanx

Hi,
you can install all .NET versions side-by-side, they don't interact.
Vista comes with most of them preinstalled.
You can install several Visual Studio versions side-by-side; they don't interact except
the one installed last will be launched when double-clicking one of the relevant
file extensions (such as .cs).

While in most cases there's no problem, you should be aware that .NET 1.x and 2.0 do collide when it comes to CAS (that's a point I had to learn the hard way).
If you set CAS policies with .NET 1.x, then these policies are not used if .NET 2.0 is installed as well. Only the 2.0 policies will be effective, even for applications running with .NET 1.1!

hi i have adde handler for html document like this but i am not able to find arguments for the event
could any one help me for this

If you're using Visual Studio, you can just click on the delegate name, hit the F12 key, and it will show you the arguments.
You can also use a class inspector tool like the free Lutz Reflector[^] to show you this information.

What I usually do is when adding the event handler, I just push tab twice, to get the following effect...
SomeObject.SomeEvent +=
SomeObject.SomeEvent += SomeEventHandler(SomeMethod);
private void SomeMethod(...) {
}Hope this helps in the future,

Heyo all,
I got this isue that I'm not able to solve for some dark reason.
I am currently working on a macro (own, independant program) that will log me in when another program (totally NOT made by me and I do not know how everything is implemented) is done loading. I can see this by a loadingbar.
Now it is not that hard to find the handle and such for this loadingbar.
So far I used (manually) Spy++ to spy on that loadingbar and noticed that when it's done loading, there aren't any messages send anymore. Which are "WM_PAINT" and "WM_ERASEBKGDN".
It is totally not important what the values are, only that the message is sent.
In Spy++ I'm able to see those messages, but in my C#-application I'm not able to.
Basically:
1. I start the other program (solved)
2. Wait until it's done loading (unsolved)
3. Type in the login information (solved)
I hope that it is clear to you that I only need code that lets me read those messages in that loadingbar and it must be possible to implement it in my C# code. Everything is ok, as long as I'm able to get a result back in my C# code, as for instance a boolean, an id of the message or the time of the message.
All I want to check is if there is no message sent for 5 seconds, so I'm sure that I can type in my login information (automated).
Thanx in advance and I hope somebody knows how to do this.

I have found many, many examples that use the SetWindowsHookEx function. But in my case they never work. Though I have never used the GetWindowThreadProcessId function before. That may make a little difference, although I've tested it with all the proccess Id's before...
I want to place a Hook into a different application of which I totally do not know how it works. So far I guess I have to inject a DLL, but how exactly I do this or what this DLL has to be able to do, I don't know.
All I want is the same functionality as Spy++ has: reading all the messages of a Window, which is in my case a loadingbar. It has it's own hwnd and such, and it receives/sends messages such as WM_PAINT (I want to read those!).
So far I'm only able to successfull place either a hook on the same process or a global hook. But those two aren't good enough for what I want to do. Though, it's rather easy to send messages to that loadingbar, so I'm realy confused why reading them should be so hard/difficult.
Thank you for your quick reply and I actually hope you can bring me a little exampe from somewhere that shows me how to place a hook on a different process totally different of the process my program is running in: exactly what Spy++ does...
I will try with the GetWindowThreadProcessId function, but I think that won't help either...

Basically, the method I would try would work as follows: First, import the two methods I mentioned in my previous response, along with some way to get the window handle for the window you are trying to log in with (such as FindWindow[^] & FindWindowEx[^]; or EnumWindows[^]). Then, use the method GetWindowThreadProcessId to get the processId (int or uint) of that window. Finally, use that processId to create a hook to listen for the WM_PAINT message. Be sure to post a response to let everyone know if this does or does not work.

I have tried your solution, but it appears not to work for me.
I haven't done any DLL Injection or something equal before, and it appears to be impossible to it only by C#. I will have to use some VC++ code to make this happen, and I don't know this code...
So far Everything is very clear to me, I even made a little project that I will share with you for a while in which you are able to see my progres.
For now I'm only able to place global hook and I have implemented the mouse-version in this project. It works fine and how it should! But the message hooks aren't working and I don't know why!
Since this is too much code to share it in here, I'll share the code with you through a .zip-file. Please note that I have been using "Visual Studio Team System 2008" Version "9.0.21022.8 RTM" and ".NET 3.5 Framework" along only "C#". Atleast you should be able to open the .cs-files with the older version aswell notepad.
Here is the link to my project: http://www.osore-watashi.net/Files/Testing_Form.zip[^]
I hope that the idea is clear: I want to get the messages from notepad in this case. An example of such message is WM_PAINT, WM_NCPAINT, WM_SYNCPAINT, WM_CTLCOLOREDIT and WM_ERASEBKGND. If you know how, please let me know!
I thank those that take the time to look for a solution for this issue.

I have found something called Managed Windows API. I am currently checking this code to hopefully find an answer to my issue.
Here is a link to it: http://mwinapi.sourceforge.net/[^]
But at this very moment I don't have the solution, so I'm still open for any ideas.

For now, this framework seems to give me a solution. Though, I haven't had the time to fully check it out, but it seems it will work.
Here I find my solution to solve the problem I think I had: the pointer to the dll-file. Here is a dll-file loaded that does the needed work (I guess) and gets the pointer to it and gives it to the SetWindowsHookEx function.
I will work this out, and as soon as I have it ready, I will give you all the code to manage it. It seems to be pretty hard to do this and it costed me a few weeks already to only find a bit of valuable information...
Keep an eye open, because this week it (normally) will be ready and will solve all your problems!

Hi all,
I'm sending a large amount of data of TCP/IP, but this causes my GUI to suspend until the send is complete. So I though put it in a delegate, but the result is the same ?? What am I doing wrong??
delegate void sendLines();
...
sendLines updInstance = new sendLines(sendManyLines);
this.BeginInvoke(updInstance);
..
void sendManyLines()
{
...
}
Thanks in advance

If this is causing the UI to freeze, why not just do the sending on another thread?

mmmm well that is what I'm trying to do, but I must update some of the controls on the form thus I require a delegate not so ??
Can you help me in this regard?
Thanks for the response

Hi,
to keep your GUI alive while a lengthy operation is being processed, you need one or more extra threads (Thread, ThreadPool, BackgroundWorker). Each of those are not allowed to
touch a Control they did not create, to solve that you need to work with Control.InvokeRequired
and Control.Invoke(). You can Google these, or read one of several CP articles on the
subject. I have a smalle example at the end of my Sokoban article.

Hi,
Is there any way i can store hexadecimal value in a XML and process the document using XMLDocument class.
Code which has problem :
string msg912 = "3...32.076.987897.89012.3073";
msg912 = msg912.Replace('.', (char)28);
string xmlData = "<pre>";
xmlData += "<port>122</port>";
xmlData += "<financialmessage><![CDATA[" + msg912 + "]]></financialmessage>";
xmlData += "";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xmlData);
a exception is thrown on loading the XML using "xmlDoc.LoadXml". How can process the XML without replacing it.
Thanks in advance.

I'm guessing it has to do with the unclosed <pre> tag. I could be wrong, as I am not familiar with the CDATA tag you are using.

I would like to write a little helper app to identify pdf files in a shared folder that have been saved as version 1.5, as they should be 1.4 or earlier to be accessible to Acrobat Reader v5
I have been looking at using FileInfo - but I guess the metadata to identify the pdf version is hidden a little deeper?
Can anyone point me in the right direction?
|
|
|
|
|
Hi,
AFAIK PDF files start with an "eye catcher" string that contains the version number.
For 1.5 it is "25 50 44 46 2D 31 2E 35 0D" in hex byte values ("%PDF-1.5"+CR).
So you should open and read the first few bytes and compare.

//Works like a charm! Ta muchly!
// 
Ignore my previous response! Having written and executed my little applet, I didn't get any results.
Which was odd, because I knew there were at least a few of these rogue files. On further investigation, it appears that the string says they are 1.4 - but are being reported on the properties-pdf tab as version 1.5. I'll dig a little deeper and get back to you.

Happy New Year Everyone!
Please help I am writing a code that searches the Active directory, it first get the list of properties, then use each property name to get its value. I filter the directory searcher by the cn. My problem is that for some people the search doesn't return the "mail" property, this is the property I need most. Please find my code snippet below.
DirectoryEntry de = new DirectoryEntry("LDAP://" + "AFLIFEDC04",
@"aflife\alsql", "perseus", AuthenticationTypes.FastBind);
string[] propertiesFound;
string Email = "";
DirectorySearcher ds = new DirectorySearcher(de);
//Use the users full name to get the email address from directory services
ds.Filter = "(cn=" + FullName + ")";
ds.SearchScope = SearchScope.Subtree;
try
{
SearchResultCollection results = ds.FindAll();
foreach (SearchResult result in results)
{
int a = 0;
ResultPropertyCollection propc = result.Properties;
DirectoryEntry dey = result.GetDirectoryEntry();
propertiesFound = new string[propc.Count];
// Loading all the properties return into the propertieFound array
foreach (string propertyName in propc.PropertyNames)
{
//This where the problem is, for some I get like 38 properties,
//for others I get 34. What is the cause of and what is the
//solution to it.
propertiesFound[a] = propertyName;
a++;
}
}
}
Thank you in advanced for your solutions.
Kind Regards
